| 摘 要： | 通过一系列试验,考察了采用不同烷烃乳液及极性添加剂作为磨削液时金刚石砂轮磨削S i3N4陶瓷时的堵塞效果。试验结果表明:由于烷烃油膜表面的非极性性质对非极性的S i3N4磨屑有很强的吸引力,采用烷烃乳液作为磨削液时,金刚石砂轮较易发生堵塞。通过在烷烃乳液中添加极性有机物,可以很大程度上缓解堵塞的发生,最佳的极性添加剂分子结构需要同时具备一定的憎水基团和亲水基团。

| Abstract: | A series of experiment are performed to test the cleaning ability of different alkane emulsion for Si3N4 ceramic grinding.The experiment results show that the adsorption film surface of nonpolar alkane has strong attraction to Si3N4 abrasive dust,which will make abrasive dust to gather at the grinding area and finally lead to jam.To add alkane grinding fluid with polar organic substances is beneficial to decrease jam.The best additive for anti-block integrates hydrophobic group and hydrophilic group,and bot... |
